Parker 3.25TEF4MAU14A08.00 Rodless Air Cylinder 250 Psi

Product Description

The PARKER 3.25TEF4MAU14A08.00 is a double acting rodless air cylinder designed for industrial pneumatic applications. It features a 3-1/4 inch bore and an 8 inch stroke, delivering linear motion without an external rod extending beyond the body envelope. The aluminum body keeps weight manageable at 12 pounds while maintaining structural rigidity under a maximum working pressure of 250 psi. A 1/2 NPTF port provides a reliable, tapered thread seal for compressed air connections. Nitrile butadiene rubber (NBR) seals provide resistance to petroleum-based lubricants commonly used in pneumatic systems. This cylinder is installed by industrial mechanics, maintenance technicians, and automation engineers working on pneumatic motion control systems.

This cylinder suits linear actuator applications where a conventional rod cylinder would create clearance or stroke-length constraints. The basic mount style allows direct attachment to machine frames, fixtures, or custom brackets. With an overall length of 12-1/4 inches and an overall width of 3-3/4 inches, it fits into compact machine envelopes. The 3/4-16 female rod thread size accommodates standard pneumatic tooling and load attachments. Typical applications include material handling equipment, packaging machinery, and general-purpose industrial automation where clean, guided linear motion is required.

Key Features

• Double acting design provides powered motion in both extend and retract directions
• 3-1/4 inch bore with 8 inch stroke for substantial force output over a compact travel range
• 250 psi maximum working pressure rating
• Aluminum body construction reduces overall assembly weight
• NBR seals compatible with petroleum-based pneumatic lubricants
• 1/2 NPTF port for leak-resistant tapered thread air connections
• 3/4-16 female thread style for standard load attachment hardware

Compatibility

Designed as an OEM-style replacement or direct-fit pneumatic actuator for industrial automation systems requiring a double acting rodless cylinder with a 3-1/4 inch bore, basic mount configuration, and 1/2 NPTF porting.

Installation Notes

Installation should be performed by qualified industrial maintenance technicians or automation engineers familiar with pneumatic systems. Depressurize and lock out the pneumatic supply line before removing or installing the cylinder. Verify that port connections are made with compatible 1/2 NPTF fittings and that thread sealant rated for compressed air service is applied per fitting manufacturer guidelines. Consult applicable safety standards and machine-specific documentation before commissioning.
